' To all whom it may concern Be it known that I, WILLIAM H. TAYLOR, residing in the city, county, and State of New York, have invented certain Improvements in Apparatus for Making Garbureted-Hydrogen Gas, of which the following is a speciiication.

The object of this invention is the production of hydrogengas from water and then carbureting it for illuminating or otherpurposes;

io and the invention consists in arranging two grates in the lower portion of a gas-generatin g chamber for supporting two masses of anthracite coal or fixed carbon, which are separated Vby a bridge-wall, and are supported over a chamber,into which air and superheated steam may be alternately forced, as will hereinafter.

appear.

The-invention further consists iu combining with said gas-generating chamber induction zo and eduction pipes and valves for air, steam, and hydrocarbon in such a manner that the introduction and discharge of the substances required in the process may be performed al, ternately from one side to the other for con- -tinuing the operation, as will hereinafter appear. i

In the drawings,-Figure l represents a front elevation of the apparatus; Fig. 2, a section or with the front wall removed. Fig. 3 is a ver 3o tical section from front to rear on line a b. Fig. 4 a horizontal section above the grate on line At A is the gasgeneratin g chamber, formed of fire-brick, and ofrectangular form, and about twice as wide asit is deep or from front to rear, so that two masses of coal placed in it will have nearly square bases, though this is not essential. This furnace-chamber is surrounded with boiler-plate, as at A', riveted at the 4o joints, and strengthened by bars of angle-iron, as at A2 and A3, and the space between is filled with sand, as at A4, sb that said chamber has great strength to resist internal pressure, and the sand serves as a non-conductor to the internal heat. -In the center of said chamber, and from front to rear, there is a division-wall, as at B, built of fire-brick or formed of slabs of the same, and extending nearly to the top of the chamber, so that it practically forms a 5o bridge-wall between the two gratos at C and D for supporting the masses of coal E and F over the ash-pits G andH in the bottom ot the chamber A. Said ash-pits also serve as chambers for air from a fan or blowing-engine of some kind to assist thecombustion, and also as steam-chambers, as will bc explained hereinafter.

At K and L, leading from the ash-pits, are pipes ofmetal lined with fire-clay or some similar refractory substance, to conduct on", rst, 6o the smoke and products of combustion from the coal, and afterward the illuminating-gas.

The upper ends of these pipes are provided with a funnel at M and N into ywhich t valves or dampers M and N', of soapstone or simi- 65 lar substance, suspended on levers M2 and N2, and provided with chains M3 and N3, to raise and close like the dampers to a furnace-chimney, so that after the smoke has passed off they may be closed, and the gas may be turned in- 7o to the branches lat O and P, and thence to the purifiers. v

In the bridge-wall B are placed the superhea-ters for the steam from which the hydrogen is obtained. These are made of metal, as shown at R, and have a partition in each at R to compel the steam from the boiler (not shown) entering at S to pass to the other end of the heater-R, and return around the end of the plate or diaphragm R', and down through 8o the` pipes S to another vheater below, and so on through the several heaters to the dischargepipe T,which enters the ash-pit below the grates rEhe coal is fed upon the gratos in the chamber A through the tunnels-or chutes at U in the arch, and they are furnished with caps having flanges at U', that it into recesses or grooves at U2, around the top of the funnels, into which sand or other substance is placed to form a seal to the caps to prevent the es- 9o cape ot' gas from `the chamber A. The air from the fan (not shown) is conducted through the main pipes W and branches W and W2, leading down t-o the ash pit or below the grates, and as shown above the furnace-doors at X, and each of these branch pipes has a wing-valve or other equivalent that is connected by a lever, Y, on the stem of the valve Y', to a sliding bar, Y2, which works in guides Y3 on the front ofthe chamber A, and said bar roo has a hand-hole or handle at one end, as at Y2 for the attendant to operate all the valves at once, and said valves are so set that when two of them are opened the other two are closed. The hydrocarbon liquid is held in tanks at Z, placed above the chamber, so it may easily flow down through the pipes Z' and Z2 into the upper corners or portion of the chamber A, and these pipes have stop-cocks, as shown at Z3, to control the flow ofthe liquid.

The operation is as follows: Both grates are supplied with a charge ot coal, as represented at Fig. 2; but the lire is started under only onesa r at D-to the mass of coal F, and the blast is turned on only under said grate and shut oft'the other. The damper at N' is closed and the one at M' is opened, so that the smoke, 85e., from the coal at F pass over the bridgewall at B and descend through the mass of coal at E and down through the grate C into the ash-pit, and thence out through the pipe K, and escape at the funnel M or past the damper M', which is shown as raised. The blast is continued in this manner until the two masses of coal are brought to an incandescent or highly-heated condition; but it is evident that the mass at E will be less heated than the other, to which the blast is first applied.

The blast is now stopped entirely, and, the

damper at M' is closed, also the pipe K, by cock at K', and then superheated steam from the heaters It is turned-on, but only under the grate C, so that it first enters the heated coal through the grate and at its lowestpoint of temperature, or at least that point farthest from the blast. It then rises up through the mass of highly-heated coal to the top of the chamber A, and as it passes over the bridgewall B meets with an incoming stream of the hydrocarbon liquid from the tank Z through the pipe Z2, when they intermingle with each other in a highly-vaporized condition, and then pass down through the mass of coal at F, which is the most highly heated of the two, and thence down through the grate D and out through the pipe L to the branch I), leading to the purifier. This operation is continued in this direction until the quality of the gas upon examination shows that the heat must be increased, when the steam and hydrocarbon liquid are both shut olf and the airblast is again turned on to increase the temperature of the coal; but this time it is turned on under the grate U, or in the reverse direction, and the mass ot' coal at E is thereby first raised to the higher temperature, and then the mass at F, and the smoke escapes out of the pipe at L and at the funnel N, the damper N being raised for that purpose and the cock at P' closed to permit the flow to the puriler. After a sufficient degree of heat is produced in the two masses of coal, as before, then the blast is shut off and the superheated steam is again turned on, but under the grate at D, and it takes the reverse direction and passes over the bridgewall at B and meets with the stream of hydrocarbon at Z', and then descends through the mass of coal at E and the grate at O, and up the pipe K, out ot' the branch pipe at O, to the purifier, and thus, by alternately reversing the blast and the supply of steam and hydrocarbon, the operation of making the gas is rendered nearly continuous in the same chamber at A. v

It is evident that various forms and the ar rangement ot' many of the parts may be introduced without departing from the nature ot' my invention; and therefore I desire to claim- 1. In a gas-generating apparatus, the combination ot a double-grated chamber, adapted for-holding two masses of coal separated by a bridge-wall, with a smoke stack or line connected to a chamber under each grate and provided with dampcrs at their outer ends, wherebythe products of combustion may be conducted from both grates alternately, as here inbefore set forth.

2. In a gas-generating apparatus, the combination of a double-grated chamber having a bridge-wall between the grates and two smokedues, one connected to the space under each grate, and provided with a damper or valve at their outer ends, with the branches O and I, for conducting the gas from the grates alternately, as hereinbefore set forth.

3. In a gas-generating apparatus, the combination ofthe doublegrated chamberA, bridgewall B, smoke-'dues K and L, dampers M' and N', branches O and l), and inlet-pipes Z' and Z2, whereby the operation of producing the carbureted gas may be conducted alternately, as hereinbefore set forth.

et. In a gas-generating apparatus, the combination of the double-grated chamber A, having a bridge-wall, B, with chambers below the grates, in combination with the steam,air, and smoke pipes for each grate, as hereinbel'ore set forth.

In witness whereof I have hereto subscribed my name and affixed my seal in the presence of two subscribing witnesses.
